👍 Nice picnic area with hiking trails near by. You could spend 20 mins just to see the rainbow eucalyptus trees or enjoy a few hours picnicking or hiking in the area. They have a decent size parking lot and even some restrooms with proper picnic tables. It can get very muddy in the rain, so be careful...
